APPARATUS FOR BLEACHING CANE-JUICE.

SPECIFICATION forming part of Letters Patent No. 483,022, datedSeptember 20, 1892.

Application filed June 6, 1892. Serial lib-436,666. (No model.)

To all whom it may-concern.-

Be it known that-I, AUGUST FERDINAND SLANGERUP, a citizen of Denmark,residing at New Orleans, in the parish of Orleans and State ofLouisiana, haveinvented certain new and useful Improvements in Apparatusfor Bleaching Cane-Juice; and I do declare the following to be a full,clear, and exact description of the invent-ion, such as will enableothers skilled in the art to which it appertains to make and use thesame.

My invention relates to an improvement in a sulphur apparatus forbleaching cane-j nice; and its novelty will be fully understood from thefollowing description and claim, when taken in connection with theannexed drawing.

The objects of my invention are to provide a new and useful device forfacilitating the clarification and defecation of saccharine solutions.

The invention Will be fully understood from the following descriptionand claim, when taken in conjunction with the accompanying drawing, inwhich the figure is a side elevation,partly in section, of my improvedapparatus.

In the said drawing, A designates an ordinary sulphur stove or furnace,and B a pipe through which sulphurfumes flow into watercylinder 0. I

D is a cock provided for controlling the flow of fumes of sulphur.

E is an overflow-pipe for water. B is the pipe which leads fromwater-chamber O and through which the fumes of sulphur pass into jnice-tank F. Resting within j uice-tank F is a perforated pipe G,provided with an elbow H, which connects with a pipe leading to a pumpK.

In practice heat is applied in the usual manner in the stove or furnaceA, and the sulphur being subjected to heat the fumes flow through thepipe B into water-cylinder O, passing along over the water in cylinderand thence through pipe B into juice-tank F, the fumes mingling with thejuice by passing out through openings G, thence through pipe to the pumpK, where by rapid movement or agitation and mingling with the sulphurfumes the juice, molasses, or other saccharine solution is clarified orlightened, thus enabling a low grade of molasses to be made light andclear and rendering the same merchantable.

I lay stress upon the agitation of the solution and sulphur fumes in thepump-casing, since by such agitation the solution is thoroughlypermeated with the fumes and the purpose of my invention facilitated.

Having described my invention and the manner in which the same is or maybe carried into operation, I would say in conclusion that I do not limitmyself to the precise details herein shown in illustration, as the samemay be varied to some extent; but

What I claim, and desire to secure by Letters Patent, is

The herein-described apparatus for bleaching cane-juice, comprising asulphur stove or retort, a water-chamber, a pipe leading from the stoveor retort to the water-chamber, the solution-tank, the pipe B, leadingfrom the water-chamber to the solution-tank and having the openings G, apump arranged in a casing, and a pipe leading from the pipe B, adjacentto the discharge end thereof, to the pump-casing, all substantially asand for the purpose set forth.

In testimony whereof I affix my signature in presence of two witnesses.

WILLIAM WILSON, LULA G. MCCARTHY.
